The true measure of success is leaving the land better than we found it.

It is not from the benevolence of the butcher， the brewer， or the baker that we expect our dinner， but from their regard to their own interest.

世界不仅仅是感觉的总和，而是一个有组织的整体。

我们为爱所做的事情往往是最不理性的。

当今天下的士人君子,内心果真想行仁义之道,做上等的贤士,上要符合圣王之道,下要符合国家与百姓的利益。
